Scientific American reports: "An isolated population of Arctic foxes that dines only on marine animals seems to be slowly succumbing to mercury poisoning." Though a definitive causal link is difficult to establish, an isolated population of arctic foxes on Russia's Mednyi Island is believed to be collapsing due to mercury contamination as a result of its seafood-heavy diet.
Where does all that
mercury in the environment come from anyway? Why, it's another biproduct of burning fossil fuels, of course, and predictably, rates of mercury pollution
are only expected to increase. In some places in the US,
even rainwater is showing high levels of contamination.

Have you ever been in a room with lots of people and not great ventilation. Or even a room with normal ventilation. You may be cognitively impaired due to elevated levels of CO2 once considered safe now thought enough to
make you a little dumb. 600ppm is now thought too much, but “there are plenty of buildings where you could easily see 2,500 ppm of CO2 — or close to it — even with ventilation designs that are fully compliant with current standards.. classrooms frequently exceed 1,000ppm."

Imagine a lake so polluted and contaminated that spending just an hour on its shores would result in certain death, and the only way seen fit to deal with it is to fill the entire water body with concrete blocks to keep the toxic soil underneath from moving onshore. That lake is Lake Karachay in Russia’s Chelyabinsk Oblast, and it is considered by many to be the
most polluted place on the planet.

Although the past 12 years have seen the warmest 10 years on record, temperatures have remained fairly steady, even while CO2 emissions grew by nearly a third. Temperatures should have been increasing during this period, rather 1998 was tied with 2010 for hottest on record. Now a
study suggests why (pdf): sulfur emissions from Asian coal plants (China mostly) are so high they mimic the effects of a volcano which can cause short term cooling by reflecting light back into space. Insidiously, the long-term warming caused by CO2 (coal) has been masked by short-term cooling of sulfur (coal).

The
long-polluted New York rivers are
getting cleaner, but can still be dangerous to swim in. There are
efforts underway to clean up the Bronx River, but that will take years, if not decades. Until then,
signs are posted, warning would-be swimmers, yet people still risk sickness to battle the heat. One current safe solution is
the Floating Pool Lady, a barge that was remade into an 82-foot-long city parks department swimming pool.
She first arrived in the Bronx in 2008, and
she'll return to the Bronx in a week. There's a new Big Idea to bring swimmers back into the rivers:
the +Pool, a floating swimming pool located within a river, designed with a series exterior walls to filter the river water and make it safe to swim in. While that's in the early design stages, you can take a chance and
jump in a swimming hole.

Coal cares! "Puff-Puff™ inhalers are available free to any family living within 200 miles of a coal plant, and each inhaler comes with a $10 coupon towards the cost of the asthma medication itself."

Yale's 2010 Environmental Performance Index (EPI) ranks 163 countries on 25 performance indicators tracked across ten policy categories covering both environmental public health and ecosystem vitality. These indicators provide a gauge at a national government scale of how close countries are to established environmental policy goals.

Waterlife — No matter where we live, the Great Lakes affect us all. And as species of fish disappear and rates of birth defects and cancer rise, it seems one thing is clear: the Great Lakes are changing and something's not quite right with the water. An interactive documentary film from the
National Film Board of Canada.

"The world’s oceans have been experiencing
enormous blooms of jellyfish, apparently caused by overfishing, declining water quality, and rising sea temperatures. Now, scientists are trying to determine if these outbreaks could represent a “new normal” in which jellyfish increasingly supplant fish.. Total jelly domination would be like turning back the clock to the Precambrian world, more than 550 million years ago."

"I don't see any future for whale species except extinction." A
report (pdf) released Thursday by
Ocean Alliance noted high levels of cadmium, aluminum, chromium, lead, silver, mercury and titanium in tissue samples taken by dart gun from nearly 1,000 whales over five years. Concentrations of chromium found in some whales was several times higher than the level required to kill healthy cells in a Petri dish. Mercury in some whales was 16 times higher than a typical shark or swordfish, both known for their high mercury levels.
Beyond whales, "You could make a fairly tight argument to say that it is the single greatest health threat that has ever faced the human species."

NASA recently released a series of photographs documenting the
loss of the Aral Sea over the past ten years. The Aral Sea could be the poster child for human damage to the ecosystem. In a mere four decades, it has gone from a surface area of 68000 km^2 to less that a quarter of that, with a 10x drop in water volume. As its
Wikipedia article points out, this is the equivalent of completely draining two of the five Great Lakes.
